This fish is similar to minnows in
shape. Because there is no pigment in the body, it
appears flesh-colored or pale red. Adults reach a length
of about 3.5 inches. As the name implies, this species is
totally blind. It can, however, move through the water
without bumping into other fish or into objects, thanks
to an extremely sensitive lateral line.

Distribution and Habitat

This subspecies is found in freshwater
pools in caves throughout central Mexico.

Diet

The diet consists of animal and plant
remains swept into the caves, as well as those included
in bat droppings that fall into the water.
